In addition, FCER2, CD200R1, and RHOV in the signature were strongly associated with the clinical stage of the tumor (Figure 12C), and univariate cox analysis showed that except for TNNT2, WT1 and KRTAP5-8, the remaining signature genes were closely correlated with the prognosis of LUAD patients (Figure 12D). The gene discussed is FCER2; the disease is neoplasm.
